----------------------------------

             Summary: ClassFormatError when property and abstract getter exist 
in the same class
                 Key: GROOVY-11634
                 URL: https://issues.apache.org/jira/browse/GROOVY-11634
             Project: Groovy
          Issue Type: Bug
    Affects Versions: 4.0.26
            Reporter: Paul King


I was exploring workarounds for GROOVY-11633 and spotted this:
{code:groovy}
abstract class MyTask {
    final Integer foo = 0
    abstract final Integer getFoo()
}
{code}
The following exception is thrown during compilation:
{noformat}
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
General error during instruction selection: java.lang.ClassFormatError: Method 
getFoo in class MyTask has illegal modifiers: 0x411

java.lang.RuntimeException: java.lang.ClassFormatError: Method getFoo in class 
MyTask has illegal modifiers: 0x411
